Curiously, this very thing happened to me just after Larry drew this comic strip. I'd been editing an existing script in SSMS and went off to watch a DVD. When I got back to work, Vista had decided to upgrade itself. SSMS didn't keep a backup of my edits and destroyed three to four hours work. I know that I should have saved my work but it never occurred to me that SSMS was so stupid as to ditch all pending work when asked to shut down by the operating system. Some IDE! My other IDEs never lose anything.
